FLOOD-GATE.

Specification of Letters Patent.

Application filed June 26, 1911. Serial No. 685,880.

may be cona novel and improved construction of outlet ate with means for operating it automatically, and also a novel structure of such operating means adapted to be actuated by an overflow of water at the head gate.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the'drawings: Figure 1 is a central vertical section through the gate. Fig. 2 is a vertical section on line 2-2 of Fig. 1. Fig. 3 is a horizontal section on line 3-3 of Fig. 1. Fig. 4 is a vertical sect-ion on line 4-4 of Fig. 3, and Fig. 5 is a detail perspective view of the out et ate.

Like numerals 0 reference refer to like parts in the several figures of the drawings.

The numeral 10 indicates the inlet chamber which is provided with inwardly inclined walls 11, which are supported at one end by posts 12 and at the opposite end by posts 13. This chamber is raised above and adapted to discharge into a fiume 14 supported at each end by posts 16. At the discharge of the inlet chamber gates 17 are provided integral with posts 18 and pivoted to the posts 13, as shown in Fig. 3. These gates are adapted to swing into the fiume, as shown by dotted lines in Fig. 3, and are held in closed position by a slide 19, which when in lowered position extends through the base 20 of the fiume 14, as shown at 21 The inlet chamber 10 may, if desired, be provided at its upper end with a head gate comprising a central support 21 and opposite side panels 22. As many of these panels may be used as is necessary to control the flow of water through the gate. The inlet chamber is also provided at one or both sides with apertures 23, communicating with a sluice way 24, which is provided with a movable gate 25. This is preferably formed in sections 25 joined by a hinge 26, which fa- 7} cable 45 extends over the drum 47. This drum also carries a smaller cilitates its removal and also placing it in position in the slots 27 formed in the sluice ways, as shown in Fig. 4, as the requirements of water supply demand. The sluice way discharges into a bucket or tank 28, suspended by a rope or cable 29 extendin over a pulley 30, upon a standard 31, ant i thence to a trip bolt 31, coiiperating with a supporting arm 32, pivoted at 33, upon the standards 34. This arm supports an operating lever 35, pivoted upon the standard 31 at 36 and connected by a link 37 with the compound lever 38. This compound lever is formed in two sections 39 and 40, connected by the hinged joint 41, section 39 being pivoted to standard 31 as at 39, while the section 40 thereof rests near one end upon a roller bearing 42 and is pivotally connected with the upper portion 43 of the inlet chamber gates 17 by means of the hinged joint 44.

The lower section of the slide 19 is connected to the cable 45 and to open the gates 17 of the inlet chamber 10, the slide 19 is moved through the medium of the lever 35, link 37, and sections 39 and 40 to clear the gates, whereupon they are swung open by the pressure of the oncoming water. The pulley 46 to the drum 48 about which a cable 49 is wound and extends over the guide pulleys 50, where itis provided with an operating weight 51. The drums also have a ratchet wheel 52 thereon adapted to cooperate with a awl 53, and the shaft 54 thereof has secured thereto an operating lever 55 by which the weight 51 may be raised into operative position and the cables wound and unwound upon their respective drums. The bucket 28 is also provided with a counterbalancing weight 56 connected thereto by a cable 57 extending off a guide pulley 58. The walls of the fiume are formed with a door 59 which may be opened to discharge the contents of the bucket 28.

In the operation of the invention when the water collects in the inlet chamber to the height of the gate in the sluice way its overflow dischar es into the bucket at the end thereof. This weight causes the trip to be released from the cross bar supporting the inlet gate lever. The upper lever then drops by gravity and breaks the joint in the compound lever through the link connection therewith. This raises the end of the compound lever connected with the retaining post of the inlet gates and lifts the lower portion thereof out of its seat in the base of the flume, and draws back the up er end of the retainin tpost. weight connected y cable and drum with this retaining post acts to throw it upward into substantially horizontal position and the gates being then released are thrown back against the walls of the flume by the pressure of the waten, so that a full flow is allowed through the gate. If this flow be too great to prevent the closing of the gates a ainst the pressure the necessary number 0% the head ates 'may be placed in osition to restrict t e pressure against t e inlet valves. When these are closed. the retaining post is inserted in position to hold them, as shown in full lines in Fig.3, and the gate in the sluiceway properly. closed to maintain the water level.

' .It will therefore be seen that this invention presents a novel, simple and economically constructed flood gate adapted to automatically control the flow therethrough and to wash out mud or other sediment which may collect in any part thereof. It also provldes an additional discharge for the water flowing through the ate and permits a eater dischar e of e water durin the odd season. T e automatic device a so regulates the feed to the canal under varying conditions of water and by its novel construction preventsthe collection of silt or debrls which would interfere with the operation of its ga'te.
